Creating Random Portfolios From List Of Assets |
Creating Random Portfolios From List Of Assets - Excel |
|
Hi there,
This is my first post (hopefully of many).
I need assistance in creating 100 random portfolios from a list of 10 assets. I have the return history of the 10 assets and I'm able to calculate the mean and standard deviation of each asset as well as the covariance/correlation between each of the 10 assets. I want to choose to portfolio with the least variance as well the portfolio with the lowest and highest return.
Would it also be possible to introduce a limit that constrains the maximum allocation to each asset at 25%?
Many thanks for any assistance on this matter.
Regards,
Grant Hogan

Random question i have a large Excel Workbook (which is protected) and has over five sheets on it - however one sheet has randomly decided not to scroll... yes i know sounds random! If i use the cursor and down arrows the selection just disappears off the screen.
The page will scroll if i filter by one field, but not if i select (All) for all filters.
All other worksheets scroll fine.
Any suggestions?
Thanks in advance.

I am creating a basic accounting spreadsheet and I ask for assistance to automate data entry posts. I would like to have entries that are entered in the general journal automatically post to the corresponding ledger accounts. The entries need to remain in chronological order. Relative cell referencing will not work because the rows in the ledgers will not correlate to the rows in the journal because the journal but the entries in the ledger need to input on the next available row in that ledger account. Additionally, as the number of entries increase, can the ledger accounts add a new row?
Attached is a very simple example with three transactions. I have included an end state view in the ledger accounts tab.
Im looking for a vlookup formula which will give me the maximum number from a list which contains multiple matches, i.e.
Lookup number 1 from column A, then give me the largest number from column B
example table:
A B
-----
1 5
2 2
1 11
3 2
4 5
the result would be 11
thanks all!
My question I believe is easily solvable for you cracks of excel.
I have a worksheet with a list of rows (item#, date, price, etc). In the last column of this list I can put an x for some of the items.
On another worksheet or sheet, I need to autoamtically have a list of the items in the first list above, that have an X in the last columns.
I created an example on a worksheet attached just for you to understand.
I apreciate all the help I can get.
Thank you so much.

Is there a way to enter a colon into a standard number to create a value that can be formatted into a 24 hour time value ?
eg a time is listed as 1345 with a general number format, and I want it returned as 13:45 witha custom format of hh:mm.
Other than creating a table and using a vlookup function, I am hoping there is a better way?

I wonder if you could help with this one, I have a list of data like this (no spaces or other characters)
JN551122B
What I need to do is split each of the characters in to its own cell
if JN551122B was in cell A1 I'd want to return:
B2 C2 D2 E2 F2 G2 H2 I2 J2
J N 5 5 1 1 2 2 B
The nearest I have got is the right function, but it brings over the preceeding characters, and I need each character in its own cell. Hopefully I could copy/paste a formula and change the reference for each cell value, i.e. 1 would return J, 2 = N, 3 = 5, 4 = 5 etc.
Thanks for your help!

so I thought I would try again.
Does anyone know of an Excel template--or a small stand-alone
program--that will calculate the interest/principal breakdown when
payments are varied in amount and frequency? Free or low-cost, please.
I need one that will work on my Mac/Office 2004. I will need to print
out periodic reports.
Here is the way the previous poster described it:
"Excel template: Loan Amortization for random/irregular payments,
figures days
between payment dates.
I have a loan with a variable beginning balance and irregular payments
with
annual large payment. (based on collections)
Would like to enter payment and date.
then Excel would figure days since last payment, interest amount,
principal
amount, Ending Principal balance.
And total interest paid, total pricipal paid
If I change the starting principal, excel would recalculate all
entries."
Thanks very much.
I can calculate the formula for this , but the problem comes where for eg there is a loss in Jan 2008 for -95415 and there was a profit in Jan 2007 for 80215. How do I set up formula to take negatives & positives into account in calculating the increase or decrease/
Your assistance or anybody's on the forum will be greatly appreciated

I am hoping for some assistance. Here is what I have....
I am trying to get counts of certain values.
This is in the same workbook but different sheets.
On sheet 1 is where my formula lies. In a cell, I want it to look at sheet 2 column B and look for instances of "A", then I want it to look in the same row it found "A" and look at the value in column "N" and evaluate if there is an amount. If there isn't skip it and don't count it, if there is a value count it if it falls within a given range.
An example of the formula is below...what am I missing?
=COUNTIF(Sheet2!B:B,(VLOOKUP(A,Sheet2!B:N,13,FALSE)=0:500))
=COUNTIF(Sheet2!B:B,(VLOOKUP(A,Sheet2!B:N,13,FALSE)=501:1000))
Thank you in advance for your assistance.
I have a spreadsheet with some cells setup with a drop-down list containing
Y, N or N/A
This is being used on a TabletPC but if I make a mistake or need to change
back to a blank field I have to invoke the soft keyboard, activate the cell
and hit backspace then close the soft keyboard - quite a long-winded
procedure just to change an incorrect choice!
What I would like to do is add a blank to the list so if I have to revert
back to a blank I can just use the stylus to choose a blank from the chooser
list.
How do I add the option of inputting a blank from the Data Validation List
bearing in mind I am using the Data Validation Source box for entering my
choices directly and not specifying a range of cells?
I have tried adding "" and even a space to no avail.
Although not a betting man I would wager there is a simple 'fix' for this
but things are only simple if you know how in the first instance! ;^)

i have a simple spreadsheet where i'm totalling a few values thru a formula. it's similar to this:
=D13*F13
i'm trying to create a funcion that says if d13 * f13 >= 300, i want the value to stay at 300 max and at the same time, if d13 * f13 < 300, i want the total to remain whatever it is.
i have been able to create both of these formulas successfully by themselves but i can't combine them. is this possible?
any help would be greatly appreciated!!
I am trying to create a formula which will look at the data in columns A - I (50 rows) and copy this data to columns K - S but ignoring any blank cells. Thereby consolidating the data in the upper rows with no spaces.
I am sure there is a relativley simple answer but it is driving me mad!
Hope you "Guru's" can help
Thanks
Added example spreadsheet to aid assistance.
Please help!!!
We have a client who will pay using the 1/4, 1/2/ and 3/4 of an hour increments as follows:
From the hour mark to 6 minutes = 0 time paid
Over 7 minutes to 15 minutes = 1/4 hour 15
16 minutes to 30 minutes = 1/2 hour 30
30 minutes to 45 minutes = 3/4 hour 45
46 minutes to 60 minutes = one hour.
They work on shifts and the operation is 24 hours. Each gets 30 minutes for breaks which is not paid. Pay is biweekly and overtime is anything over 40 hours. Currently, the template we are using looks like this (sorry, I could not figure out how to paste it so you can see it in Excel layout):
WEEK 1 Sunday Monday Tuesday Wednesday Thursday Friday Saturday
5/16 5/17 5/18 5/19 5/20 5/21 5/22
TIME IN ENTER TIME, INCLUDE AM OR PM

Im working with a large data spreadsheet that has Yes and No answers in different columns. There are blanks within the selection too.
I need to calculate only the Yes.
I have tried using the filters in the Pivot Table field list and they are not working.
So now i'm trying to add a COUNTIF formula in the Calculated Fields section.
The formula I'm using is =Countif('Time limit extension'="yes") and i get the answer "too few."
What should I be using in the formula to get the calculated field to work? I have search the whole forum and I haven't found an answer that can help me.
Please HELP!!!
jumps way down the page to what appears to be a random cell. The one i
originaly typed in remains blank. spreadsheet was previously ok this has
just started to happen.
help please
thanks
For example: Cell A1 has a time format (hh:mm) value of 04:00; which is the Start Time. I would like cell D1 to have a text format value of "04:00" (result is dependant upon what is entered in A1). I would duplicate the same formulas to reflect Stop Times in other cells.
My final result is to have another cell (F1) use the Concatenate formula to have the Start and Stop time shown in one cell as "04:00 - 12:30". The times would change based on the Time formated values entered into the Start and Stop time cells.
I have researched this in the board and found many excellent ways to do the opposite, but not convert Time format to Text format. Any assistance is greatly appreciated.
